This is a high value - low cost, pre-aligned single
reflection ATR accessory. When compared to more expensive
single reflection designs, its sensitivity is equally
impressive for qualitative and quantitative analysis.
The unique 45 degree ZnSe internal reflection element,
combined with the two mirror assembly for beam entry to the
sample and return to the instrument's detector, provides for
minimal energy loss and records an average 85 percent open
Other design features include the ability to easily remove
and clean or replace the ATR crystal from its mechanical
mount assembled with the flat or trough top plate. This
convenience permits interchange between other ATR crystals
without having to purchase complete top plate assemblies. A
kalrez gasket incorporates an assured seal for the top plates and eliminates problems associated with designs using epoxy. The gasket does not interact with the sampling radiation, thus spectra are free from spurious peaks or energy degradation.
The standard order details provide for a single reflection accessory with a 45 degree ZnSe flat top plate, pressure clamp, volatiles cover and flexible tubes for purge maintenance.
Additional options include a ZnSe trough top plate, heated
solid and liquid top plates, liquid flow-through cell and
spare 45 degree ZnSe, Ge or ZnS prisms.
